The Application of Microtremor Exploration Technology in the Detection of Hidden Disaster Causing Geological Factors in Coal Mines
Microtremor exploration technology has been widely used in complex geophysical environments with strong interference and non destructibility due to its advantages such as no need for artificial sources,strong anti-interference ability,high resolution,convenience and environmental protection.This paper takes the detection of goaf in Gaoyang coal mine,Shanxi Province as an example to conduct research on the application of microtremor in the detection of hidden geological factors causing disasters in coal mine,used linear array for mi-crotremor data collection and Jiaojia surface wave processing software to extract dispersion curves,and then inverting to transverse wave velocity profiles,identifying 16 anomalies.Based on the analysis of 16 anomalies and the wave velocity characteristics of hidden disaster causing geological factors such as goafs,collapse columns,and faults,this paper concludes that the linear array microtremor method has a good application effect in identifying the a-bove hidden disaster causing geological factors in the mining area.
